- Exercises in Programming Style with Hazelcast
-
It was a fun experiment at the time: using Hazelcast In-Memory Data Grid to solve the problem explained in the book Exercises in Programming Style.
- How to Streamline Data Access With Valet Key Pattern?
-
I never thought about this pattern; it’s pretty neat!
- A year of uv: pros, cons, and should you migrate
-
I migrated from
pip, topip-tools, and now I’m on Poetry. The more I hear aboutuv, the more I want to try it. - Docs
-
Amazing initiative from a joint initiative between the French and the German governments. In these troubled times, it’s good to see Europe making efforts to win back its digital sovereignty. Icing on the cake, the solution can be self-hosted.
- Get the Most Out of GitHub Copilot
-
I wanted to see how GitHub Copilot was advertised, and not only I wasn’t convinced, but I think the presentation does harm the product.
I always try to avoid relying on the Cloud at during my talks: it’s unreliable by default. If I have a talk, which contains a demo, and one late step of the demo relies on the Cloud, I can always get away with it; if your whole presentation relies on the Cloud and it’s not available, how are you going to get away with it?
Worse, the presenter knew that during this specific week, GitHub Universe would take place and would hammer the server. Why didn’t he prepare for it?
When you’re doing a demo that relies on the Cloud, always have a backup video!
- Crate borrow
-
Zero-overhead "partial borrows", borrows of selected fields only, including partial self-borrows. It lets you split structs into non-overlapping sets of mutably borrowed fields, like
&<mut field1, field2>MyStructand&<field2, mut field3>MyStruct. It is similar to slice::split_at_mut but more flexible and tailored for structs.Partial borrows offer a variety of advantages. Each of the following points includes a short in-line explanation with a link to an example code with a detailed explanation:
- The Art of Argo CD ApplicationSet Generators with Kubernetes
-
After all this time, I must definitely start playing with Argo CD.
- Propagating OpenTelemetry context when using Virtual Threads & Structured Concurrency
-
OpenTelemetry propagates its context outside across threads using
LocalThread. With Virtual Threads, this approach doesn’t work anymore. The post shows how to do it manually; I hope the library evolves to take care of it soon enough. - Fastrace: A Modern Approach to Distributed Tracing in Rust
-
My OpenTelemetry demo features a Rust component using Axum. Every time I upgrade one of the libraries I’m using for distributed traces, I run the risk of breaking something. After I do, I’m often unable to detect the issue and I have to rollback. I definitely would love a simple macro-based approach, like the one described:
#[fastrace::trace] async fn get_user(Path(user_id): Path<String>) -> Json<User> { // Standard log calls are automatically associated with the current span log::info!("Fetching user {}", user_id); let user_details = fetch_user_details(&user_id).await; Json(User { id: user_id, name: user_details.name, email: user_details.email, }) } - Architecture Diagramming Tools, and the AI Gap
-
My current ones are:
- PlantUML, since it integrates nicely with Asciidoctor
- Excalidraw for non-UML stuff
- The CIDR House Rules
-
Good explanation of CIDR, with examples.
- Evolving Scala
-
More than ten years ago, Scala was very popular in the JVM world. I got interested in the language myself, passing the Functional Programming Principles in Scala course on Coursera in 2012. I found it somewhat interesting, but didn’t pursue.
Over the years, I maintained a slight interest in the language, until I bought into Kotlin. Developers regularly mentioned two technical problems–I won’t mention the toxic community: flawed IDE integration and slow build tools.
It’s funny to see that more than twenty years after its inception, the language creator has big plans to address them. Why so late? More importantly, what are the chances that these big plans will be successful, compared to the same big plans years ago?
